Application Notes
Commercial and Industrial Grade Products
1.0 INTRODUCTION
This application note outlines the differences between the products of the commercial and industrial grade, and
focuses on explaining the differences of Chrontel’s production classification and products management policy for the
commercial and industrial grade products.
2.0 THE DIFFERENCE OF COMMERCIAL AND INDUSTRIAL PRODUCTS
Generally, the products of electronic components and semiconductors are classified to commercial and industrial
grade according to the ambient operation temperature and the tolerance of power supply. For the commercial grade
products, the ambient operation temperature is from zero degree C to 70 degree C, and the tolerance of power supply
is within 5%. And for the industrial grade products, the corresponding specifications should be from minus 40 degree
C to 85 degree C and 10%.
The differences are determined by the applications actually. In fact and generally, the commercial grade products are
used in commercial electronic devices, in which the products’ application environment is stable and under room
temperature, not likely to be subjected to industrial temperature or power supply variations. The industrial grade
products are used in devices or systems including industrial measurement and control, automotive, network and other
high reliability systems, in which the application environment is harsher and of more variations. So, the industrial
grade products need more reliability, stability and performance than the commercial grade products.
Besides the differences mentioned above, Chrontel’s industrial grade products are generally distinguished from the
commercial grade products by products’ part number, with a special character ‘I’ added to the suffix of the part
number and is marked on the top surface of the chip.
3.0 THE DIFFERENCE OF OPERATION AND POLICY
The following chapter described the details of the differences in operation and policy for commercial and industrial
grade products.

EOL Notification
Note: Package Change is a change of the products’ package type or a change of assembly house. Wafer/die Change is
a change of the products’ internal circuitry or a change of wafer foundry. EOL is the products’ end of life.
Product changes are typically identified by a products’ unique date code and /or part number as default.
3.5
Product Support
The industrial grade products are treated more strictly on the verification of products’ quality than the commercial
grade products, customer support priority of the industrial grade products is also generally arranged by Chrontel to be
higher than which of the commercial grade products, which covers all the technical and operation support, including
and not limited by the software customize support, products feature documentation on customer request, PCN release
if necessary and products’ preparation and lead time support.
